This replaced an older brother machine. It does take about 30-45 mins to set-up (as per all the other reviews), but then works well wirelessly. Brother machines scan thru very quickly and then fax or print (if you're copying) as opposed to other brands which do 1 page at a time. Slight lag before printing (as with all wireless printers). Toner cartridges are amongst the cheapest out there - use the high-capacity TN-450.
I mainly bought the printer for my iPad. It was not easy like the Canon, which I had to return, to wireless print. I had to call Brother and go through name, rank and serial number to get any information! I was then transferred to an Indian lady and had to go through part of the same thing again. If the information she is going to email me to download does not work, I am returning the printer! I don't like to pay big money and have to go through a big hassle. At least this printer is a little faster than the one I had. I prefer the Epson printers, but they have been downgraded over the years.
